Two cars belonging to the president of Serie A strugglers Pescara were set alight in an arson attack blamed Tuesday on hardline “ultra” fans upset at the club’s poor form.

President Daniele Sebastiani said he planned to quit the crisis club after a Smart car and an SUV were torched, according to reports. Police were alerted by neighbours who saw one of the vehicles engulfed in flames.

Serie A condemned the “indescribable acts of violence” and Sebastiani said he had “had enough” and would quit at the end of the season, according to Il Centro newspaper.

“We hope those responsible are brought to justice as soon as possible. Intimidation or violence is not to be tolerated, especially by a president who has always run his club with immense passion and commitment,” said a league statement.

Police in Pescara are studying closed circuit television cameras near the scene following the incident.
